The very underated sex version of Mary Shelley's novel. A bit sleezy, for sure, but great fun anyhow. too bad Joseph Cotten had to vanish so early on the film. He made a very dashing Victor Frankenstien. Even though the monster is quite terrifying and ugly, he gets occasions to get laid. that's the big irony of the film. Star Rosalba Neri is credited "Sara Bay" for the U.S. version.

The director is none other than Mel "Gravis Mushnik" Welles from Roger Corman's "The Little Shop of Horrors" a decade earlier.
Check for the theatre posters of this one: the most colorful and provocative you could find!
